IPC: B65H31/30
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal matching of sheets by delaying a moving speed in drawing the plural sheets from a bin when the loading numbers of plural sheets, loaded on the bin, are many, or, when a loading direction length is long.

Title: Connection condition detection device, and medium with built-in ic chip provided with the circuit
Inventor: AZUMA HIDEJI
IPC: G06K19/07
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To suppress the power consumption, and to improve the reliability. SOLUTION: When the applied timing signal from an IC control part 101 is in an enable condition, a PMOS transistor 20 for a pull-up resistor is in an energized condition through an inverter circuit 10. When a wire 80 to be detected is connected, the divided resistance voltage to be inputted in an AND circuit 70 through an intermediate lead is higher than the logical threshold at the AND circuit 70, and the connection condition signal to be outputted is on the HIGH level. When the wire 80 to be detected is disconnected, the divided resistance voltage to be inputted in the AND circuit 70 is only dependent on an NMOS transistor 60 for a pull-down resistor, and since the divided resistance voltage is lower than the logical threshold at the AND circuit 70, the connection condition signal to be outputted from the AND circuit 70 is on the LOW level.  Thus, the connection or disconnection can be judged.

Title: Data processor
Inventor: MASUI TOSHIYUKI
IPC: H04B1/10
Filed: 1983-12-14
Abstract: PURPOSE:To simplify the circuit constitution by limiting the number shifting a data of signal amplitude in a low-order bit direction in a data processor muting the output. CONSTITUTION:While a counter circuit 13 conducts counting, the data subjected to pre-value holding by a latch circuit 5 is outputted as it is. When the counter circuit 13 is stopped, the clock number applied to an S-P converter 9 becomes (n-1+k), the value of 1/2k of the data subjected to pre-value holding is outputted sequentially, the muting is finished and the output data goes to 0 level. When the flag data restores 0 again, the clock number of the T period decreases from 2(n-) to (n-1), the value of 1/2<k> of (n-1)-bit data inputted to a P-S converter 8 is outputted sequentially and the release of muting is finished. The data representing the amplitude is muted gradually by simply changing the control block number of the S-P, P-S converters 9, 8 or the muting is released.

Title: Thin film dielectric
Inventor: TERADA KOSUKE
IPC: H01L21/316
Filed: 1991-09-17
Abstract: PURPOSE:To obtain a thin film dielectric which is high in permittivity and breakdown strength, small in leakage current, and long in service life by a method wherein dielectric thin films of high permittivity and thin films of dielectric material low in leakage current are alternately laminated for the formation of the thin dielectric concerned. CONSTITUTION:A stripe-like transparent electrode 2 of ITO is formed on a glass board 1 through a high frequency sputtering method. Ta2O5 layers 3 and Al2O3 layers 4 are alternately and repeatedly laminated thereon through a high frequency sputtering method. The laminated dielectric is of four or more-layered structure, and it is preferable that it is of 18 or more-layered structure. As high permittivity dielectric material coexists with high-breakdown strength.low leakage current dielectric material in the obtained thin film dielectric, the obtained thin film dielectric becomes higher in permittivity than the thin film which contains only high-breakdown strength.low leakage current dielectric material. The thin film dielectric is more enhanced in breakdown strength and lessened in leakage current as compared with the thin film dielectric which contains only high permittivity dielectric material. Therefore, when a thin film dielectric of this design is applied to an EL element, the EL element can be enhanced in luminance and lowered in driving voltage.

Filed: 1992-09-03
Abstract: PURPOSE:To obtain a module which remains reliable for a long term by using elastic adhesive to secure solar cell panels on a metal roof and thereby absorbing warps due to the difference in thermal expansion coefficient. CONSTITUTION:An elastic adhesive (Young's modulus: 10<6>-10<8>dyne/cm<2>) containing silicon is used to attach bendable solar cell panels 201-204 to a metal roof 101. At that time bubbles are prevented from entering between the solar cell panels 201-204 and the metal roof 101, and the panels are attached in turn from the end of the solar cell module. This absorbs warps arising from the difference in coefficient of thermal expansion between the metal roof 101 and the solar cell panels 201-204. Further, no rack is required for the installation of the solar cell module; accordingly, the weight is reduced, and no troublesome work is required.
